Member Enumeration Documentation

enum MoochoPack::FeasibilityStepReducedStd_Strategy::EQPObjective

Enumeration values: OBJ_MIN_FULL_STEP  min 1/2 * (Y*wy + Z*wz)'*(Y*wy + Z*wz) OBJ_MIN_NULL_SPACE_STEP  min 1/2 * wz'*wz OBJ_RSQP  min qp_grad_k'*wz + 1/2 * wz'*rHL_k*wz Definition at line 65 of file MoochoPack_FeasibilityStepReducedStd_Strategy.hpp.

enum MoochoPack::FeasibilityStepReducedStd_Strategy::EQPTesting

Enumeration values: QP_TEST_DEFAULT  Decide based on olevel input to compute_feasibility_step(...). QP_TEST  Perform the tests. QP_NO_TEST  Don't perform the tests. Definition at line 76 of file MoochoPack_FeasibilityStepReducedStd_Strategy.hpp.
